You are very welcome Sigs. Eve
Hi Sigs,
My advice if for your son to make an appointment with his family doctor.
I have asthma myself and have had asthma for many years now.
My asthma was diagnosed by my doctor at the time. If your son thinks
this may be the start of asthma, he should see his family doctor as soon
as possible to see if he indeed has asthma. I wish you and you son well. Eve
